TENDER-HOSE COUPIQING.

lessees;

vnew and 'useful Improvement in Tendery Hose Couplings, of which thefollowing is 2 is a plan View ot' the coupling.

a t'ull, clear, and exact description, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, formingpart of thisspecification. h

My invention relates to new and useful improvements in pipe couplingsand particularly to such couplings as are utilized in the tubularconnections between a locomotive boiler and tender. These connectionsusually include a metallic pipe carried by the locomotive and a sectionof flexible tubing carried by the tender and it is the principal objectof my invention to provide a simple, inexpensive coupling for theadjacent ends otI the tubular connections justmentioned and whichcoupling is capable ot' being quickly connected or disconnected.

A further object of my invention is to `provide a coupling ot the classdescribed that is perfectly water tight when connected and said couplingbeing provided with means adapted to lock the two parts thereof to e-achother so that said parts are etfectually and firmly held togetherregardless of thel jolting and vibration to which the coupling issubjected in service.

lo the above purposes my invention consists in certain novel features ofconstruction and arrangement of parts hereinafter more fully describedand claimed.

Figure l is a side elevation ot' a coupling of my improved construction.Fig. F 3 is a horizontal section taken on the line 2 2 of Fig. l.

Referring by numerals to the accompanying drawings, 1 designates ametallic pipe and 2 the flexible hose, which parts are united by myimproved coupling.

3 designates a shell that is substantially hemisphcrical in torni andprovided with an internally threaded nipple 4 which receives thethreaded ond ot the pipe 1. Formed within the shell 8 just below itsedge is an annular rib or flange 5 which Atorms a seat for the edge ot astrainer of perforated metal or suitable Wire mesh. Formed onSpecification' of VLetters Patent.

top ot' the shell. 3 is anoutwardly project ing bifurcated lug` 7 andformed on the opposite side ofsaid shell and projecting forwardlytherefrom is a horizontally disposed ear or lug 8 that is provided Wit-han open 'ing 9.

10 designates a shell, thel main body portion of which is substantiallylike' the shell 3 and formed on or fixed to said shell is a' tubularextension 11 which receives the end ol the flexible tube 2. Formed onthe in side ol the shell 10 around the edge thereof and projectingoutwardly therefrom is a continuous flange 12, which, when the parts or"the couplings are united, extends into the chamber within the shell 3immediately ad jacent to the edge of the strainer 7. This flange 12forms a support for a packing ring or gasket 13 that occupies a positionbetween the edges of the shells 3 and 10 when the same are unitedFormedy onthe sides ot the shell 10 are lugs 14 provided-v witb notches15, wliicli latter serve as seats for the sides of a split ring 16. Thisring is made in the form of a yoke having an extension 17 on its solidside, which extension fits in the opening 9 When the parts areassembled. The split side of the ring 16 is provided wit-h a pair oflugs 18 and piv-u otally connected to these lugs by means of a pin 19'isthe biturcated end of a bolt 20, which latter passes through thebifurcated lug T and its threaded end receives a nut 21. The purpose ofsplitting the ring or yoke 1G is to enable it to be sprung over the endsof the lugs 14 so that the side portions of said yoke or ring can beseated in the notches 15. After the yoke or ring has thus been seated inthe notches 15, the ends provided with the lugs 1t, are. broughttogether and connected to the bifurcated end of the bolt 20.

When the two parts of the coupling are to be connected, the shell 1() isbrought into position immediately in front of the shell and theextension 17 is inserted through the opening il. 'l`he bolt 2O is nowswung downward into position within the biturcated lug 'i' atter whichthe nut 21 is tightened upon said bolt, thus dri-.wingr the upper end ofthe split ring toward the bifln'cated lug and causing the sides ot saidsplit ring to fulcrurn on the lugsI ll, thereby exerting equal pressureentirely around the contacting` Vai-es ot the shells Il and 10. r|`hepacking y ring or gasket 13 positioned between said contacting faces .isby this action compressed and thereby forms a tight joint between parts3 and 10.' To disconnect the parts of the coupling, the nut 2l isloosened until the bolt 2O can be swung upward out of the bifurcated lug7 and the shell l0 can now be disengagedffrom the shell 3 by lifting theextension 17 from the opening 9. The split ring or yoke 16 and the bolt20 provide simple means for firmly connecting the two parts of thecoupling and forming a water tight joint between the contacting faces ofsaid members and the entire coupling is comparatively simple, comprisesa minimum number of parts and forms an efficient coubling for thetubular connections between a locomotive boiler and tender.

While I have described my improved'coupling as being` particularlyintended for use in the tubular connectionsbetween a locomotive boilerand tender, it will be readily understood that practically the same formof coupling may be advantageously used between the adjacent endsofitubes wherevera readily detachable couplingis desired.

It will be readily understood that minor changes in the size, form Aand-construction of the various parts of my improved coupling can be madeand substituted for those herein 'shown and described without departingfrom the spirit of my invention, the scope of which is set forth in theappended claim.

l claim:

In a coupling of the class described and in combination, a pair oftubular members having complemental faces to oppose each other withpacking therebetween, one of said members being adapted to be secured toa rigid support and having a perforated lug on one side and a bifurcatedlug on its opposite side, said perforated lug projecting substantiallyparallel to the axis of the members with the perforation extendingtransversely to the direction of lengt-h of the lug, said perforationbeing positioned in advance of the face of the member by which it iscarried, a split ring carried by the other member and formed with aprojection operating as a male element with respect to said carrying anelement adapted to unyield-y ingly contact with said lug rear .face bymovements longitudinally of the'bolt when said element is in engagementwith said rear face, whereby said members may be coupled by the use ofone hand. i

In testimony whereof l hereunto affix my signature in the presence of,two witnesses, this 11th day of June, 1912.
